The Spokane County Sheriff’s Office reported on Twitter just before 12:30 p.m. that northbound lanes of Sullivan Road had reopened after the collision, which was reported around 7 a.m., according to a news release. Southbound lanes are expected to remain closed throughout the afternoon as crews clean up the spill, estimated at about 500 gallons.

One of the trailers involved in the collision rear-ended the other headed southbound on Sullivan, just north of the park on the banks of the Spokane River.

There were no injuries reported in the collision.

Motorists are advised to use alternate routes while the cleanup continues. An investigation into the incident is continuing.
